1 relay protection development present situation

The electrical power system rapid development to the relay protection proposed unceasingly t he new request，the electronic technology, computer technology and the communication rapid development unceasingly has poured into the new vigor for the relay protection technology de velopment，therefore，the relay protection technology is advantageous, has completed the deve lopment 4 historical stage in more than 40 years time.

After the founding of the nation，our country relay protection discipline, the relay protection de sign，the relay manufacture industry and the relay protection technical team grows out of noth ing，has passed through the path in about 10 years which advanced countries half century pa sses through. The 50's，our country engineers and technicians creatively absorption, the diges tion，have grasped the overseas advanced relay protection equipment performance and the m ovement technology，completed to have the deep relay protection theory attainments and the rich movement experience relay protection technical team, and grew the instruction function t o the national relay protection technical team's establishment. The acheng relay factory introd uction has digested at that time the overseas advanced relay manufacture technology，has est ablished our country relay manufacturing industry. Thus our country has completed the relay p rotection research，the design, the manufacture, the movement and t he teaching complete sys tern in the 60’s. This is a time which the mechanical and electrical relay protection prospers，was our country relay protection technology development has laid the solid foundation。

From the end of the 50’s，the transistor relay protection was starting to study。In the 60's to t he 80's in are the times which the transistor relay protection vigorous development and widely uses。Tianjin University and the Nanjing electric power automation plant cooperation research 500kv transistor direction high frequency protection the transistor high frequency block system which develops with the Nanjing electric power automation research institute is away from th e protection, moves on the Gezhou Dam 500 kv line , finished the 500kv line protection to d epend upon completely from the overseas import time.

From the 70’s, started based on the integration operational amplifier integrated circuit protectio n to study. Has formed the complete series to at the end of 80’s integrated circuit protection，substitutes for the transistor protection gradually。The development, the production, the applica
